The M-1 carbine is a fun gun.
Back in the '60-'70s, if a GI carbine couldn't be found, there was Plainfield and Universal. Their replicas got cheaper as surplus parts dried up. I avoided them and lucked out in finding a Saginaw (GM steering gear) one for $100 in '77. Snatched it up without hesitation from the gun store.
The M-1 Carbine was the first rifle I liked as a youth. I have an IAI (Israeli) aftermarket one. The rear sight blade fell off after a few shots and being in the field, I couldn't find it. I bought a picatinny rail that replaced the handguard and will put a Tasco red dot on it.
